darthcamaro writes "For nearly three years, Oracle has had its own version of Red Hat Enterprise Linux, claiming the two versions are essentially the same thing. But are they really? As it turns out, there are a few things on which Oracle and Red Hat do not see eye-to-eye, including file systems and virtualization. The article quotes Wim Coekaerts, Oracle's director of Linux engineering, saying, 'A lot of people think Oracle is doing Enterprise Linux as just basically a rip off of Red Hat but that's not what this is about. ... This is about a support program, and wanting to offer quality Linux OS support to customers that need it. The Linux distribution part is there just to make sure people can get a freely available Linux operating system that is fully supported.'"
